SELF-CLOSING wmoow.

SPECIFICATION forming part of Letters Patent No. 790,370, dated May 23, 1905.

Application filed September 6,1904. Serial No. 223, i69.

To aZZ whom it may concern.-

Be it known that I, FREDERIOK O. KAscrr, a citizen of the United States, residing at Akron,

in the county of Summit and State of Ohio,

have invented a certain new and useful Improvementin Self-Closing Windows, of which the following is a complete specification.

My invention has relation to self-closing Windows.

The object of my invention is to provide a window having sashes movable vertically in a window-casing and hung and balanced by counterweights in the ordinary manner and which in case of fire in the vicinity of the winto lighten the upper sash which previously, with its supplemental Weight, accurately bal-. anced its counterweight, thus rendering it so light that it will readily close, due to the action of its counterbalance-weight, and at the same time impose the displaced weight upon the nicely -balanced lower sash, the 1 added weight of which will overcome its counterblalance-weight and cause it to automatically 0 ose.

Another object is to provide said window with suitable devices for maintaining the transferable weight normally in the upper sash and to release the same on the occasion of a fire in the vicinity, allowing it to be deposited in the lower sash.

To the accomplishment of the aforesaid objects my invention consists in the novel and peculiar construction, combination, and arrangement of the various parts hereinafter described, reference being had to the accompanying drawings.

In the accompanying drawings, in which similar reference-numerals indicate like parts .1n the dliferent figures, Figure 1 is a View of the interior of a window with parts of the casing and sashes in section to better illustrate the same; Fig. 2, a front view, enlarged,

cated by the line X in Fig. 2 with reference to the upper sash. Fig. 4 is a front view of the opening in the upper sash, in which is placed a fusible link for holding the weightreleasing mechanism normally in position; and Fig. 5, a section of Fig. 4 at the line Y. In the drawings, 1 represents the lower sash, 2 the upper sash, and 3 the window-casing. These may be of wood, but are preferably of hollow sheet metal made in any pre ferred manner as to the formation of the seams uniting the various parts together. These sashes are each vertically movable by hand in the casing in the ordinary way of opening and closing windows, and each is accurately balanced by counterweights 4, hung on cords or wires 5 over pulleys 6. The upper bar of the upper sash is made somewhat wider than is ordinarily the custom, and being hollow there are formed therein at each end pockets 7, the floors of which are septums 8, tapering upward as they approach the center of the bar. These floors or s'eptums 8 extend down into the hollow side bars of the sash, with one of their sides inclined downward toward the inner side of the window. In the inner walls of the side bars are cut openings 9, through which openings the ends of the septums 8 extend, forming downwardlyinclined projecting shelves.

Riveted or otherwise suitably fastened to both of the inner faces of the side bars of the upper sash and immediately about the openings 9 are tubes 10, generally formed with a rightangled offset top which incloses the openings 9 and into which project the extended ends of the septums 8. The main bodies of the tubes 10, which are preferably made rectangular, but may be of any cross sectional configuration, extend downward vertically parallel with and.slightly separated from the side bars of the sash and enter openings in the top of the upper bar of the lower sash on a line with the hollow portion of the side bars thereof. When both sashes are '7 would unless otherwise held in check immediately pass through the openings 9 into the tubes 10 and from thence into the hollow frame of the lower sash, and thus effect a change of weight in the sashes by lightening the upper and weighting the lower to a degree equal to the amount of weight transferred. In weighting the upper sash I prefer to employ shot as being one of the best agents for this purpose, fulfilling all requirements of cheapness and mobility. In order to hold this shot in the tubes 10 and pockets 7 I place in the tubes 10, near their lower ends, small weights 11, freely slidable therein, but of such a size as will effectually check the downward movement past them of. any of the matter constituting the weighting substance.

Extending through the septums 8, the pockets 7 openings '9, and into the centers of the vertical tubes 10, I fasten as preferred tubes 12, properly curved, through the interiors of which are passed freely-slidable wires 13, to the lower ends of which are connected the check-weights 11, thus serving to normally hold them in position. The upper or inner ends of these wires 13 are attached to the two members of a link 14:, held together by a solder fusible at a low degree of heat. This link let (see Figs. 4 and 5) is placed in an opening cut through the sides of the central portion of the upper bar of the upper sash and is held by the following mechanism.

In the openings in both walls of the upper Sash are placed cup-shaped open members 15 and 16, which are drawn toward each other against a thin metallic plate 17 by screws 18. The link 14 is held by a readily-fusible solder to the outside of this plate 17, thus holding it at all times centrally in position, but at all times exposed to the action of fire without the building directly and through the plate 17 to fire in the room. This plate 17 serves also to prevent the entrance into the room of dust, snow, rain, &c.

The parts being normallyin the position shown and the sashes open, the result in the event of fire in the vicinity of the link will be the simultaneous parting of the members of the link, the immediate dropping of both check-weights 11 below the ends of the tubes 10 into the lower sash, and the depositing of the weighting material in the hollow frame of the lower sash. This transfer of weight will so lighten the upper sash, which. had heretofore been balanced, that its ordinary sash-weights will close it and the superimposition of the added weight to the previously carefully balanced lower sash will cause it to close by overcoming its counterweights.

What I claim is- I 1. A self-closing window consisting of two sashes, a weight in the upper sash, means to normally hold it there and means to transfer it to the lower sash.

2. A self-closing window consisting of two sashes, a weight carried in the upper sash, means to hold said weight normally in position, a fusible link to hold said means in check and means to transfer said weight to the lower sash on the parting of said link.

3. A self-closing window, consisting of a hollow sash, a transferable weight held within the body of the sash, tubular outlets connecting with the interior of said sash to permit the escape of said weight, means involving a fusible link to hold said weight in said hollow sash and means arranged to open said tubular outlets and permit the escape of said weighton the parting of said link.

4. A self-closing window, consisting of a hollow sash, a transferable weight normally held without the body of said sash, means involving a fusible link to keep said weight from said sash and means to deposit said weight in the hollow of said sash on the parting of said link.

5. The combination in a self-closing window, of two sashes, transferable weights in the frame of the upper sash, means including a fusible link to normally hold said weights in place, means to conduct said weights to the interior of the frame of the lower sash on the parting of the members of said link.

6. The combination in a self-closing window, of upper and lower sashes with hollow frames, weight-holding pockets in said upper sash, tubes extending from said pockets to the interior of the lower sash, check-weights in said tubes to hold back said weights, and a link the members of which are held together by a fusible solder connected with said checkweights.

7 The combination in a self-closing window, of upper and lower sashes with hollow frames, vertical tubes projecting from the upper sash and extending into the lower sash and slidable therein, weight-carrying pockets in the upper sash connecting with the upper ends of said tubes, checks in said tubes to normally hold back said weights, a fusible link suitably mounted in said uppersash and means to connect said link and checks.

8. The combination in a self-closing window of a hollow-framed upper sash,.counterbalance-weights for said sash, means in the said sash for carrying a transferable weight which with the sash will evenly balance its counterweights, a lower hollow-framed sash which evenly balances its counterweights and means for conducting said transferable weight from the interior of said upper sash to the interior of said lower sash.

9. The combination in a self-closing window, of two hollow-framed sashes, means for ing in the upper sash.

10. A device for holding fusible links in an opening" in Window-sashes, consisting of two oppositely-disposed hollow members seated in IQ the opening, a thin plate, to which the link is fusibly soldered, and means to clamp said plate between said members and across said opening.

In testimony whereof that I claim the above I hereunto 'set my hand inthe presence of tWo 5 subscribing Witnesses.
